Hi all, I recently bought some pearls and believe they are tahitian undyed pearls, but am not sure. Is there any way to tell if they are dyed? Many thanks for any help or info. They are a gorgeous black peacock color with 14k clasps and solid gold beads. The pearls have gorgeous overtones of black, purple, mauve, blue and green. Both of the gold, locking clasps are marked 14K and the beads are also gold. The necklace measures 18" long and the bracelet is 8". The pearls are a good size and between 7-8 mm. Both pieces have a substantial weight of 40.6 grams together and are in very good condition.
